Did You Know?

1. St. Augustine grass is not native to St. Augustine, Florida. Despite its name, the grass is actually native to the shores of the Mediterranean Sea.
2. St. Augustine grass is highly salt-tolerant, which makes it a popular choice for coastal areas. It can withstand exposure to salty air and even some saltwater flooding.
3. Unlike many other grasses, St. Augustine grass reproduces primarily through stolons rather than seeds. Stolons are above-ground runners that allow the grass to spread horizontally, creating a dense turf.
4. To encourage St. Augustine grass to spread, one effective method is to “plugging”. This involves cutting small plugs from existing healthy areas of the lawn and transplanting them to bare spots, allowing them to establish and grow.
5. Mowing St. Augustine grass too short can actually hinder its ability to spread. It is recommended to maintain the grass at a height of 3 to 4 inches to promote healthy growth and allow it to fill in any thin or bare areas.

St. Augustine Grass: Heat And Drought Tolerant

St. Augustine grass is highly favored for Texas lawns due to its exceptional heat and drought resistance. This grass variety can endure soaring temperatures and demands less water compared to other types. Moreover, it is renowned for its ability to withstand foot traffic, making it an ideal choice for lawns frequently used for recreational activities or gatherings.

What makes St. Augustine grass truly remarkable is its rapid regrowth and spreading capacity when properly tended to. If your lawn has bare patches, this grass will swiftly fill them in, resulting in a lush and even surface. However, achieving this level of spread necessitates appropriate soil conditions, regular maintenance, and proper care.

Soil Conditions For Spreading St. Augustine Grass

To encourage the spread of St. Augustine grass, it is crucial to provide the right soil conditions. This grass variety can grow in various soil types with a pH range from 5.0 to 8.5. Ideally, the pH of the soil should be between 5.0 and 7.5, and it should not be high in nitrogen.

Moist soil is preferred for St. Augustine grass, but it is essential to avoid waterlogged or compacted soil. Waterlogged soil restricts oxygen flow to the roots and can hinder growth. To combat this, the use of topsoil can be beneficial, as it helps reduce water accumulation in the soil. Before planting St. Augustine grass, it is recommended to test the soil to ensure it meets the optimal conditions for growth and spread.

The Importance Of Proper Soil pH And Moisture

In addition to the soil conditions, it is crucial to maintain the appropriate pH level and moisture content for the successful spread of St. Augustine grass.

  • Sandy or well-draining soil is highly recommended, as it allows for proper water distribution and prevents water pooling in uneven or bare areas.

Achieving the correct pH level is also essential. St. Augustine grass thrives in a pH range of 5.0 to 8.5, with the ideal pH falling between 6.0 and 7.5.

  • Testing the soil and making any necessary adjustments can significantly contribute to the health and spread of the grass.

St. Augustine Grass Maintenance: Fertilizing, Watering, And Mowing

Regular maintenance is necessary to ensure the growth and spread of St. Augustine grass. Fertilizing, watering, and mowing play vital roles in maintaining a healthy lawn.

When it comes to mowing, it is crucial to adhere to the recommended height. The ideal mowing height for St. Augustine grass is between 3.5 to 4 inches. It is important not to cut more than 1/3 of the leaves in a single mowing to avoid stress on the grass.

Fertilizing is essential to promote growth. During the first 3 to 4 months after installation, it is recommended to use a high phosphorus fertilizer. This helps establish a robust root system and supports overall growth. After this initial period, transition to a normal nitrogen fertilizer to maintain the health and density of the grass.

Watering plays a significant role in the spread of St. Augustine grass. For the first 7 to 10 days after installation, it is important to water the grass multiple times a day. This encourages root development and strong establishment. On day 11, irrigate the grass with at least a half inch of water. Gradually decrease irrigation after week six, allowing the grass to adapt to the regular watering routine.

  • Adhere to the recommended mowing height (3.5 to 4 inches)
  • Avoid cutting more than 1/3 of the leaves in a single mowing
  • Use a high phosphorus fertilizer for the first 3 to 4 months after installation
  • Transition to a normal nitrogen fertilizer for maintenance
  • Water the grass multiple times a day for the first 7 to 10 days after installation
  • Irrigate the grass with at least a half inch of water on day 11

Weed Control For Optimal Growth And Spread

To ensure optimal growth and spread of St. Augustine grass, it is essential to control weeds. Weeds can hinder the spread of the grass and prevent it from growing faster and thicker.

Treating weeds before they germinate can be an effective approach to weed control. Using a pre-emergent herbicide during the appropriate months can help prevent weeds from taking root and competing with the St. Augustine grass.

Specific types of weeds, such as dallisgrass, crabgrass, and broadleaf weeds, are known to slow the growth and spread of St. Augustine. Monitoring and promptly removing these weeds can help maintain the health and density of your lawn.
